The giraffes of Africa – the long and short of it
It’s hard to comprehend that giraffe numbers have plummeted by almost 40% in just three decades. This rapid slide now places them amongst the most threatened species on the planet, with only approximately 98,445 individuals remaining across this massive African continent!
A population collapse of this nature could conceivably be driven by that evil Far East cabal of wildlife traffickers that perpetuate myths about how wild animal parts can improve health, wealth and happiness. In this case, though, it would appear that the now-familiar threats of habitat loss, degradation and fragmentation coupled with human population growth and illegal hunting (poaching) are to blame.
I would imagine that its large size makes it difficult for giraffes to pass through dangerous human-occupied territory unnoticed, and surely the return for the effort of killing a giraffe is high, what with all of that meat on the hoof.
“We do not have any evidence of giraffe in traditional Chinese medicine, but in all honesty, a detailed trade assessment is required to understand local and potential international trade better. At this stage, we are aware of the bushmeat trade in different countries and the interest in tails as fly swatters (dowry for brides) in northern Kenya and DRC.” – Dr Julian Fennessy, Giraffe Conservation Foundation (GCF)
Here then, is a summary of what you need to know about the giraffes of Africa, with the information provided by the Giraffe Conservation Foundation (GCF). This is the long and the short of it.
Giraffes, as a species, are listed as ‘Vulnerable’ according to IUCN, which means that they are vulnerable to extinction in the near future. Updates for most of the currently recognised subspecies are under review by IUCN, with updated status assessments expected soon, in mid-2018.
There has been limited conservation effort and research on giraffes across Africa, and so, to aid conservation efforts going forward, GCF has compiled historical and current data on giraffe numbers, distribution and threats from across their range in Africa. This work has been undertaken collaboratively with African governments, NGOs, universities, IUCN and independent researchers.
There are four distinct giraffe species in Africa, and two of these species have two and three subspecies respectively. All live in geographically distinct areas across Africa and do not cross-breed in the wild (they have been known to do so in zoos).
Masai giraffe (Giraffa tippelskirchi)
The Masai giraffe is often noticeably darker than other species. Its blotches are large, dark brown and distinctively vine leaf-shaped with jagged edges, separated by irregular, creamy brown lines.
It ranges through central and southern Kenya and throughout Tanzania, with a geographically isolated population (potentially subspecies) in the South Luangwa Valley in Zambia. This Zambian population was previously mistakenly assumed to be Thornicroft’s giraffe, but they are genetically identical to the Masai giraffe. A small number have been translocated into Akagera National Park in Rwanda – outside of their natural range. Historically the most populous of the species, recent reports of poaching suggest that their population is decreasing. The population estimate is 32,500 individuals.
Reticulated giraffe (Giraffa reticulata)
The reticulated (or Somali) giraffe has brown-orange patches which are clearly defined by a network of thick and striking white lines. This species is found predominantly in central, north and northeastern Kenya, with small populations and range persisting in southern Somalia and southern Ethiopia. It has been estimated that about 8,700 individuals remain in the wild (likely more with new counts being undertaken) – down from an approximate 31,000 as recently as 1998.
Southern giraffe (Giraffa giraffa)
The southern giraffe has two subspecies:
1. Angolan giraffe (G. g. angolensis)
The Angolan giraffe’s pattern extends down the legs and is made up of large, uneven and notched spots against a white (or cream) to the tan-coloured background. This subspecies is found in most parts of Namibia, central Botswana and Zimbabwe. They went locally extinct in Angola until recent private translocations. Some have been translocated into DRC, South Africa, Zimbabwe, Nigeria and other parts of Botswana – outside of their natural range. The population is estimated at 13,050 individuals.
2. South African giraffe (G. g. giraffa)
The South African (or Cape) giraffe’s pattern extends down the legs and is made up of large, uneven and notched spots on a background that is more tan-coloured than white or cream. This subspecies is found across South Africa, Botswana, northeastern Namibia, southwestern Zambia and some areas in Zimbabwe, with conservation re-introduction efforts into Mozambique. Previous extralimital introductions of this subspecies and of Angolan giraffe into their known range are likely to have resulted in hybrid populations in those areas.
There have also been introductions of South African giraffe beyond their natural range, in South Africa, Angola, Senegal, Swaziland and Zambia. The population is estimated at more than 39,000, making this the most populous species.
Northern giraffe (Giraffa camelopardalis)
The northern giraffe has three subspecies:
1. Kordofan giraffe (G. c. antiquorum)
The Kordofan giraffe’s spots are pale, large and rectangular. It has no markings below the hocks. This species is found in some of Africa’s more unstable areas: southern Chad, Central African Republic, northern Cameroon, northern Democratic Republic of Congo and western South Sudan. Most of these populations were previously incorrectly assumed to be G. c. peralta. The population is estimated at 2,000 individuals.
2. Nubian giraffe (G. c. camelopardalis)
Nubian giraffes have large, rectangular blotches set irregularly against a cream background. The lower legs are noticeably white and not patterned. The Nubian giraffe has the same Latin name as that of the entire species because it was the first specimen recorded. Recent research has shown that the two subspecies, previously known as Nubian and Rothschild’s giraffe, are actually genetically identical, and so Rothschild’s giraffe has been subsumed into the Nubian giraffe. This subspecies ranges across eastern South Sudan (information about large herds unconfirmed), western Ethiopia, northern Uganda and west-central Kenya. The majority of Nubian giraffe in Kenya are outside their natural range.
In 2015 and 2016, Nubian giraffes were (re-)introduced into Uganda’s Lake Mburo National Park and the southern bank of the Nile River in Murchison Falls National Park respectively after an absence of 100 years or more. The population is estimated at 2,645 individuals.
3. West African giraffe (G. c. peralta)
The West African (or Nigerian) giraffe is noticeably light in appearance, which rectangular tan blotches separated by thick, cream-coloured lines, often with no patterning on their lower legs. After being widely distributed at the beginning of the 20th century from Nigeria to Senegal, this subspecies now inhabits an isolated pocket east of the Niger capital of Niamey, sharing their living space with local villagers. No other large wild mammals remain in this region. By the 1990s, only 49 individuals remained, and after direct intervention by the Niger government, their number has risen to approximately 550 individuals (and counting).

Giraffe Action Fund
The Giraffe Action Fund (GAF) is an exciting GCF initiative that aims to secure and increase current numbers and distribution of giraffes throughout their range in Africa. Their action plan includes securing additional habitat, anti-poaching efforts as well as conservation education and awareness. In the last year alone, more than US$500,000 has directly gone to support partners efforts in giraffe conservation and management efforts.
Specific GAF projects:
- Saving Uganda’s threatened Nubian giraffe
GCF and the Ugandan Wildlife Authority (UWA) signed a memorandum of understanding in 2014 to conserve this threatened giraffe subspecies. Once free-ranging across western Kenya, western Ethiopia, southern South Sudan and Uganda, the Nubian giraffe has been largely eliminated from much of its former range. GCF’s giraffe conservation efforts in Uganda focus on all three national parks that host giraffe: Murchison Falls, Kidepo Valley and Lake Mburo national parks.
- Murchison Falls National Park
Murchison Falls National Park hosts by far the largest population of Nubian giraffe in the wild (1,250 estimated), and GCF are undertaking a long-term study on giraffe numbers, their distribution and ecology – in close collaboration with UWA and Dartmouth College. The recent discovery of oil in the park and the threat of poaching incursions (mainly via wire snares) from the Democratic Republic of Congo, which lies just across the River Nile, are significant challenges.
- Operation Twiga I & II
Two critical translocations of giraffes have taken place to increase their range within Uganda – known as Operation Twiga (twiga is Swahili for giraffe). The translocations took place in Murchison Falls National Park in 2016 and ‘17 – from the northern side of the Nile River (where oil was discovered) to the southern side. In total, 37 giraffes were successfully moved and continue to be monitored. In April 2018, the first two calves were observed in this new population – a great conservation success!
- Kidepo Valley National Park
GCF has undertaken the first-ever and subsequent, annual giraffe census in Kidepo Valley National Park. The current estimate of only 36 Nubian giraffes (from three in 1902), means that further conservation efforts are needed to ensure a viable population. Operation Twiga III is planned for mid-2018, and the aim is to augment the existing population by 10 Nubian giraffes from Murchison Falls National Park. Poaching has stopped, but the giraffes are still under threat by habitat loss, fragmentation, and disease.
- Lake Mburo National Park
Giraffes disappeared from Lake Mburo National Park about 100 years ago, probably due to poaching and disease. Re-introducing giraffes from Murchison Falls National Park into Lake Mburo National Park for ecological and ecotourism reasons was done in July 2015, and in April 2018 the first calf was born in this new population. While poaching is minimal around the park, the giraffes’ new home is under pressure from expanding human populations around the park and increasing demand for land. The giraffe population is still small and needs all our support to help it grow to play a valuable role in this landscape once again.
Giraffe translocation: Operation Twiga
Below is a series of photos showing Operation Twiga in full swing.
Starting top left: The giraffes are darted and captured (1) to have a blindfold and ropes attached (2 & 3) and data recorded (4), before being woken up and led into a high-sided truck (5) for transportation (6) to a boma (7). They are then loaded into a larger truck for ferrying across the Nile River (8) before being re-released. All photos © Giraffe Conservation Foundation

Celebrating Africa’s Giraffes
The 21st June marks the summer and winter solstice, and in the northern hemisphere, it is the longest day of the year. It is then entirely appropriate that the day also marks World Giraffe Day, considering it is the planet’s longest-necked animal. With their beautiful eyes and regal bearing, the giraffe is a remarkable creature that deserves recognition and praise.
